Mini mini spoilers: The keycards were spelling out the combination you had to enter using the four buttons under the bottom left monitor! If I had more time I would've made that part of the game a little more clear. Once the voting is over maybe :)
aaaaaah, I thought that was it but I couldn't see my cursor change to the pointing hand you get when you can interact with stuff when lookig at the buttons, so I didn't bother haha
